Vuetify-Form-Base

Imagine you get the following data as JS-Object and your Task is to design a Form to edit this data

Value: {
	name: 'Jumo',
	position: 'Coder',
	tasks: [
		{ 
		  done: true,
		  title: 'make refactoring' 
		},
		{ 
		  done: false,
		  title: 'write documentation'  
		},
		{ 
		  done: true,
		  title: 'remove logs'  
		}        
	]        
}

Normally you have to flatten the Data-Structure and map all to an appropriate Format. Then you have to define a HTML-Form and animate it with your Data.

With Vuetify-Form-Base create a Schema Object with the same structure as your Data.

Schema: {
	name: {
		type:'text', 
		label:'Name'
	},
	position: {
		type:'text', 
		label:'Position' 
	},
	tasks: { 
		type: 'array',
		schema: { 
			done:{ type:'checkbox', label:'done', flex:3}, 
			title:{ type:'text', flex:9 }
		} 
	}
}

and you will get a full reactive and editable Form:

If you have to generate forms or you have to edit Data presented as JSON- or JS-Objects, then take a closer look at Vuetify-Form-Base and try it. It can make your work much easier and save you time. This Form Generator works as Vue.js 2.0 Component and can simplify your Job by automatically creating Forms, based on your Schema-Definition. Edit your created Forms and you will automatically receive reactive Results.

Vuetify-Form-Base uses the well known and excellent Component Framework Vuetify to style and layout your Form. Vuetify Controls have a clear, minimalistic design and support responsive Design.

Intro

vuetify-form-base is a Vue Component and can easily integrated into any Vue Project.

The Schema-Object has the same structure as the Value-Object. Create a Schema by cloning the Value-Object and replace the Values of the Data-Object by Definitions for your your Schema. The corresponding Schema-Object defines type, layout and functional behaviour of the Controls in your Form.

The Component Framework Vuetify styles your Form. The Controls have a clear design, but don't worry if you need more you can change your style in a lot of ways. For more details see section Style with CSS

Based on an existing Value-Object vuetify-form-base generates a full editable Form. Layout and Functionality are defined in a Schema-Object, which has the same Property structure as the Value-Object. Your Data-Object keeps full reactive and any Input or Change in your Form triggers an Event too. If you have a deep nested Value-Object or an Array-Structure you can direct work on it. There is no need to flatten or modify your Data Presentation.

Changing any Field in the Form gives you a reactive Result in your Value-Object. Furthermore you can synchronize two or more Forms by using same Value-Object.

If you want a Partial-Form which displays only parts of your Data.Object, then link a property of your Data-Object to your vuetify-form-base Component.

And if necessary you can also build a Form in Form by using Slots.

Use the v-on directive of Vue.js to listen to Formbase triggered Events for 'Resize', 'Focus', 'Input', 'Blur', 'Click', 'Mouse' and 'Swipe'. Listening to 'Change' will catch all Value changing Events like 'Input' and 'Click'. 'Watch' will listen to 'Focus', 'Input', 'Blur' and 'Click'. Listening to 'Update' will catch all Events.

Installation

For proper working you need a Vue.js Project with Vuetify 2.0 installed. For more Details see Vuetify 2.0 Quickstart.
After a successful installation of a VUE project with Vuetify 2.0

npm install vuetify-form-base --save

vuetify-form-base is a Vue.js single-file component with a .vue extension and you can use it like any Vue-Component.

In order for your application to work properly, you must wrap it in a v-app component. This component is required and can exist anywhere inside the body, but must be the parent of ALL Vuetify components. v-content needs to be a direct descendant of v-app.

    <template>
      <v-app>
        <v-content>
          <v-container fluid>
            <v-form>
              <v-form-base :value="myValue" :schema="mySchema" />
            </v-form>
          </v-container>   
        </v-content>
      </v-app>
    </template>

	import VFormBase from 'vuetify-form-base';  

    export default {	
      components:{ VFormBase },
      data () {
        return {
          myValue: {
            name: 'Jumo',
            password: '123456',
            email: 'base@mail.com',
            checkbox: true,
            select: 'Jobs',
          },   
          mySchema: {
            name: { type: 'text', label: 'Name' },
            password: { type: 'password', label: 'Password' },
            email: { type: 'email', label: 'Email' },
            checkbox: { type: 'checkbox', label: 'Checkbox' },
            select: { type: 'select', label: 'Select', items: ['Tesla', 'Jobs', 'Taleb'] }
          }
        }
      }
    }

and you will get a full editable Form based on your schema and filled with your Value-Object.

INFORMATION:

Properties in 'myValue' without corresponding Prop in 'mySchema', are ignored and keep untouched, but a initial warning will be logged to console

Example displaying nested Data-Object

In Reality sometimes you will have deep nested objects or arrays, which should be edited. vuetify-form-base works for you and flatten internally this nested object and build a plain Form.

      myValue: {
        name: 'Base',
        controls:{
          selection:{
            select: 'Tesla',
            selectM: ['Jobs'],
          },
          switch: [ true,false ],
          checkbox: [ false, true, { 
            checkboxArray: [ true, false ]}
          ]
        }       
      },

      mySchema: {
        name: { type: 'text', label: 'Name'},
        controls:{
          selection:{
            select: { type: 'select', label: 'Select', items: ['Tesla', 'Jobs', 'Taleb'] },        
            selectM: { type: 'select', label: 'M-Select', multiple:true, items: ['Tesla', 'Jobs', 'Taleb']}
          },
          switch: [ 
            { type: 'switch', label: '1' }, 
            { type: 'switch', label: '2' } 
          ],
          checkbox: [
            { type: 'checkbox', label: 'A' },
            { type: 'checkbox', label: 'B' }, 
            { checkboxArray: [
              { type: 'checkbox', label: 'C-A', color:'red' },
              { type: 'checkbox', label: 'C-B', color:'red' }
            ]}  
          ],
        }
      }

Example editing Data-Arrays

For editing arrays use the type 'array' and define an nested 'schema' property.

    mySchema: {
      tasks: {
        type: 'array',
        schema: { 
          done: { type: 'checkbox'  }, 
          title: { type: 'text' }
        }
      }  
    }

Type Array - Schema object

    myValue: {      
      tasks: [
        {
          done: true,
          title: 'make refactoring'
        },
        {
          done: true,
          title: 'write documentation'
        },
        {
          done: true,
          title: 'remove logs'
        }
      ]
    },
    mySchema: {
      tasks: {
        type: 'array',
        schema: { 
          done: { type: 'checkbox', label: 'Ok', flex: 3 }, 
          title: { type: 'text', flex: 8 },            
        }
      }
    }

Computed Schema

IF you want Schema Properties to be changed dynamic, then you must make your Schema Object a computed property. This Example turns the Radio Layout from Column to Row on Resizing to medium Size or greater.

    data () {
      return {
    
        myValue: {
          radio: 'A',
        }
    
      }   
    },
    computed: {          
    
      mySchema(){ 
        return {
          radio: { type: 'radio', row: this.row, options:['A','B'] }
        }
      },
    
      row () {
        return this.$vuetify.breakpoint.mdAndUp 
      }
    },

Vuetify Layout and Grid

Integrate Vuetify Grid by using the Schema-Properties 'flex', 'offset' and 'order':

    mySchema: {
      name: { type: 'text', flex: 4, offset: 2, order: 1 },
    }

flex: 4     // shorthand for flex: { xs:4 }
offset: 2   // shorthand for offset: { xs:2 }
order: 1    // shorthand for order: { xs:1 }

A more responsive Solution with 'flex', 'offset' or 'order' needs an Object as Value. For more Details see Vuetify Documentation:

Vuetify - Grid: flex: { xs:12, sm:8, md:6, lg:4 }

Vuetify - Offset: offset: { xs:0, sm:1, md:2, lg:2 }

Vuetify - Order: order: { xs:1, sm:1, md:2, lg:2 }

Link & Synchronize

Forms can be linked together using the same Value-Object. Changes in one Form are synchronized and reflected in the other Form.

	<v-form-base :value="myValue" :schema="mySchema" />

	<v-form-base id="form-sync" :value="myValue" :schema="mySchema" />

Vuetify Controls API-Props

Vuetify Controls have a API with Props These Props in Vuetify-Controls comes in kebab-case amd must for use in Schema-Object converted to CamelCase

<!-- vuetifyjs.com -->
Input & Controls
  Text-fields
    API-Props   
      append-icon
      background-color 

<!-- JS -->
mySchema: { 
  name: { type:'text', appendIcon:'menu', backgroundColor': 'red' },
  ...
}

Schema

<form-base :schema="schema" ... />

Schema is an JS-Object, which defines and controls the behavior of your Form. Each Key Prop) in your Schema-Object must reflect a Key from your Data-Object. A minimalistic Definition of a text input could look like this:

schema:{
  name: { type:'text'}  
}

The next shows a more complex Schema:

    // Partials Functions for Rules
    const minLen = l => v => (v && v.length >= l) || `min. ${l} Characters`
    const maxLen = l => v => (v && v.length <= l) || `max. ${l} Characters`
    const required = msg => v => !!v || msg
    const validEmail: msg => v => /.+@.+\..+/.test(v) || msg
  
	// Destruct Value and return a Value! 
    const toUpper = ( {value} ) => value && value.toUpperCase() 
    
    export default {
    
      components: { VFormBase },
      data () {
        return {
          
          myValue: {
            name: 'Base',
            password: '123456',
            email: 'base@mail.com'
          },
                  
          mySchema: {
            name: { 
              type: 'text', 
              label: 'Name', 
              hint:'Converts to UpperCase'
              toCtrl: toUpper, 
              fromCtrl:toUpper,
              rules: [ required('Name is required<>) ] 
              flex: 12, 
            },
            password: { 
              type: 'password', 
              label: 'Password', 
              hint:'Between 6-12 Chars', 
              appendIcon: 'visibility', 
              counter: 12, 
              rules: [ minLen(6), maxLen(12) ], 
              clearable: true, 
              flex: 12 
            },
            email: { 
              type: 'email', 
              label: 'Email', 
              rules: [ validEmail('No valid Email'), required('Email is required<>) ], 
              flex: 12 
            }
          }
        }
      }
    }

Available Properties in Schema ( NEW: PICKERS and FILE-INPUT available )

For further Props see Vuetify Controls API

schema:{
  
  type: string            // text, password, email, file, 
                          // radio, switch, slider,
                          // combobox, autocomplete, select,  
                          // date, time, color    

  sort: N                 // use simple order to display items 

  order: N or Object      // use Vuetify-Grid to order items responsive 
  flex: N or Object       // See Vuetify Grid
  offset: N or Object     // See Vuetify Grid

  label string,           // label of item    
  placeholder: string,    // placeholder 
  hint: string,           // additional Info  
  tooltip: string | bool  // show tooltip - use Slots for individual text

  color: string
  backgroundColor:string
  css: string,            // inject classnames - schema:{ name:{ css:'small'}, ...  }
    
  mask: string,           // regex to control input  

  multiple: bool,         // used by type: select, combobox, autocomplete    
  required: bool,         // need an input value
  hidden: bool,           // hide item - set from another item
  disabled: bool,         
  readonly: bool,          
        
  appendIcon: icon        // click triggers event with icon-location
  prependIcon: icon       // click triggers event with icon-location

  items: array            // ['A','B'] used by type: select, combobox, autocomplete   
  options: array,         // ['A','B'] used by type:radio
  rules: array of Fn      // [ value => true || false, ... ]
  
  // must return a (modified) value!!
  toCtrl: function,       // ( {value, obj, data, schema} ) => value	
  fromCtrl: function,     // ( {value, obj, data, schema} ) => value
}

Events

We can use the v-on directive to listen to vuetify-form-base events 'focus', 'input', 'blur', 'click', 'mouse', 'resize', 'swipe', 'update' and run some Code when they’re triggered.

This Example use the Default ID and listen all events with 'update':

    <!-- HTML -->
    <v-form-base :value= "myValue" :schema= "mySchema" @update= "update" />

The next Code has the Custom ID 'form-base-simple'. In this case your v-on Directive must append the Custom ID like @update:form-base-simple:

    <!-- HTML -->
    <v-form-base 
      id = "form-base-simple" 
      :value= "myValue" 
      :schema= "mySchema" 
      @update:form-base-simple= "update" 
    />

You can also listen to an specific event. Your v-on Directive must append the Custom ID:

    <!-- HTML -->
    <v-form-base :value= "myValue" :schema= "mySchema" @blur= "blurCode" />
   
    <v-form-base 
      id = "form-base-complete"
      :value= "myValue" 
      :schema= "mySchema"  
      @click:form-base-complete= "clickCode"
      @input:form-base-complete= "inputCode"
      @change:form-base-complete= "changeCode"
      @watch:form-base-complete= "watchCode"
      @focus:form-base-complete= "focusCode"
      @blur:form-base-complete= "blurCode"
      @mouse:form-base-complete= "mouseCode"
      @swipe:form-base-complete= "swipeCode"
      @resize:form-base-complete= "resizeCode"
      @update:form-base-complete= "updateCode"     
    />

Listen to one or more of following events

    @input= "change"
    @click= "change"
    @change="change" // input & click
    @watch= "change" // focus & input & click &  blur
    @focus= "change"
    @blur=  "change"
    @mouse= "change" // mouseenter & mouseleave
    @resize="change"
    @swipe= "change"
    @update="change" // catch all events

The Event-Signature:

    change( {  on, id, key, value, params, obj, data, schema, parent, index, event } ){
      // destructure the signature object 
    }

on -        Trigger Name  // focus|input|blur|click|resize|swipe|update 
id -        Formbase-ID
key -       key of triggering Element
value -     value of triggering Element
obj -       triggering Element { key, value, schema } 
event -     the native trigger-event if available 
params -    params object if available { text, x, y, tag, model, open, index }    
index -     index of array of schemas  
data -      Data-Object
schema -    Schema-Object
parent -    Formbase-Object - if available

Example: Use 'Update' Event to control Visibility of Password Element

    <!-- HTML -->
    <v-form-base :value="myValue" :schema="mySchema" @update="update">

    <!-- JS -->
    // Schema
    mySchema: {
      password:{ type:'password', appendIcon:'visibility', .... }
    }
    
    ...
    
    update ({ on, key, obj, params }) {
      // test event is 'click' and comes from appendIcon on key 'password'
      if (on == 'click' && key == 'password' && (params && params.tag) == 'append') {         
        // toggle icon
        obj.schema.appendIcon = obj.schema.type === 'password' 
          ? 'lock' 
          : 'visibility'

        // toggle visibility 
        obj.schema.type = obj.schema.type === 'password' 
          ? 'text' 
          : 'password'
      }
    }

Slots

Use Slots to pass Header and Footer into a Control. If necessary replace Controls by Slots. Any slot could be a v-form-base component itself.

   <v-form-base :value="myValue" :schema="mySchema" @update="update">

     <h4 slot="slot-top-key-name">Top Slot on Key Name</h4>
     <h4 slot="slot-top-type-radio">Top Slot on Types Radio</h4>
     
     <h4 slot="slot-item-key-password">Slot replaces Key Password</h4>
     
     <h4 slot="slot-bottom-key-name">Bottom Slot Key Name</h4>
     <h4 slot="slot-bottom-type-radio">Bottom Slot on Types Radio</h4>
     
     // Tooltip see css.vue in Example 
     <div slot="slot-tooltip" slot-scope="slotProps">
       {{ slotProps.obj.schema.tooltip }} has value '{{ slotProps.obj.value }}
     </div>
   
   </v-form-base>

Try CSS & Slots in Example

Form Validation

If you need Form Validation you have to wrap v-form-base with v-form and take the reference of v-form for working on.

    <!-- HTML -->    
    <v-form ref="form" v-model= "formValid" lazy-validation>
      <v-form-base :value= "myValue" :schema= "mySchema" @update= "update"/>
    </v-form>

    <!-- JS -->
    validate () {
      this.$refs.form.validate()
    },

    resetValidation () {
      this.$refs.form.resetValidation()
    },

Style with CSS

Customize your vuetify-form-base component using CSS-Classnames

IMPORTANT:
Don't use <style scoped> in parents component, because scoped definitions are inside the child component not accessable

Formbase - ID

#form-base is the default ID of your component. If you need different CSS for two or more forms in the same parent component, then change default value by setting a different ID for each component and use this new ID. Using a 'custom-id' you have to modify the event-binding to @update:custom-id = "update"

    <!-- Default ID CSS-Style -->   	
    #form-base {...}

    <!-- HTML-Template -->   
    <v-form-base @update= "update" />

    <!-- Custom-ID CSS-Style -->   	
    #custom-id {...}

    <!-- HTML-Template -->   
    <v-form-base id="custom-id" @update:custom-id= "update" />

General - Classname

#form-base  {...}

Type - Classnames

Style all items of a specific type, then use type specific classnames. They start with type- appended by any type. You can use following types in your Schema-Object:

'text', 'email', 'password', 'textarea', 'select', 'autocomplete', 'combobox', 'radio', 'checkbox', 'slider', 'switch', 'date', 'time'

#form-base .type-text { color: #44A }}           	  
#form-base .type-email { font-weight:500; }

Key - Classnames

Set Classname of deep key in your Data-Object, by converting .dot notation 'person.adress.city' into kebab case 'person-adress-city' prepending 'key-'

<!-- 
    myValue{ person:{ adress:{ city:'',... } ... } ... } 
  CSS Classname to access to key 'city'
-->
#form-base .key-person-adress-city { font-weight:500; }    


<!-- 
  Access to myValue: { name:'' }
  CSS Classname to access key 'name' 	       
-->
#form-base .key-name { font-weight:500; }            

<!-- 
  myValue: { controls: { slide: [25, 64]  } 
  Access First Entry in Array of Key Slide 
-->
#form-base .key-controls-slide-0 { font-weight:500; }

Validate with Pseudoselectors

#form-base .item input:valid { background-color: #afa; }
#form-base .type-email input:invalid { background-color: #faa; }
#form-base .key-name input:focus { background-color: #ffd; }

CSS - Example

<!-- JS -->
myValue: {
    name: 'Base',
    password: '123456',
    email: 'base@mail.com',
    controls: {
      checkbox: true,
      switch: true,
      slider: 33,
      radioA: 'A',
      radioB: 'B'
    }
  }

 <!-- CSS  -->
<style>
  #form-base { 
    border: 1px solid #cb2; 
    background-color: #ffe; 
    padding:2rem 
  }
  
  /* CSS Item --- set all items  */
  #form-base .item { 
    border-left: 1px dashed #29D; 
    border-top: 1px dashed #29D; 
    padding:1rem 
  }

  /* CSS Type --- set all items with type */
  #form-base .type-switch { border-bottom: 3px solid #E23}
  #form-base .type-checkbox { background-color: #fdd }

  /* CSS Keys --- select key in object 'myValue.controls.slider' */
  #form-base .key-controls-slider { background-color: #fec }
</style>
